関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a solenoid valve, and more particularly to a solenoid valve suitable for use in a blow-off and sorting machine for powder particles. .
［従来の技術］ 本考案の考案者は、実開昭61-23579号公報において、粉
粒体の吹飛ばし選別機に好適な２ポート電磁弁を提案し
た。[Prior Art] The inventor of the present invention has proposed, in Japanese Utility Model Publication No. 61-23579, a two-port solenoid valve suitable for a blow-off and sorting machine for powder and granular material.
この種の電磁弁は、高速度かつ高頻度での開閉が要求さ
れるために、可動弁の肉厚を薄くして質量を小さくする
必要がある。また、磁性材よりなる可動弁が電磁部に吸
着すると、残留磁気で可動弁の復帰速度が遅くなるとと
もに衝突によって破損の恐れがあるので、可動弁を電磁
部に衝突させないように案内することが必要である。Since this type of solenoid valve is required to open and close at high speed and with high frequency, it is necessary to reduce the thickness of the movable valve to reduce the mass. If the movable valve made of a magnetic material is attracted to the electromagnetic part, residual magnetism slows the return speed of the movable valve and may damage it due to collision.Therefore, guide the movable valve not to collide with the electromagnetic part. is necessary.
したがって、上記公知の電磁弁においては、磁気板に、
可動弁の案内と衝突を防止をする案内緩衝部材を設けて

ために、構成が複雑で大形になるばかりでなく、案内部
の径が大きいために肉厚の薄い可動弁がガタついて傾斜
し易く、このため、案内及び緩衝機能を十分に発揮する
ことができない場合がある。Therefore, in the above-mentioned known solenoid valve, the magnetic plate is
A guide cushioning member for guiding the movable valve and preventing collision is provided. However, since the guide cushioning member guides the outer peripheral surface of the movable valve, not only the structure is complicated and large, but also the guide portion Since the diameter of the movable valve is large, the thin movable valve rattles and tends to incline, so that the guide and cushioning functions may not be sufficiently exerted.
［考案が解決しようとする課題］ 本考案が解決しようとする課題は、小形で簡単な構成を

している。[Means for Solving the Problems] In order to solve the above problems, a solenoid valve of the present invention has a plurality of ports and a plurality of through holes provided in a passage for communicating these ports with a valve seat at the rim. Energize the exciting coil with a shaped valve seat and a valve section having a flat movable valve made of a magnetic material, and an exciting coil, a fixed iron core, and an electromagnetic section having a magnetic frame surrounding the exciting coil. In the electromagnetic valve in which the electromagnetic portion attracts the movable valve to open the valve seat, the cylindrical cushion made of an elastic material attached to the valve portion side of the fixed iron core prevents the movable valve from colliding with the electromagnetic portion. And a plurality of shoulders for applying a restoring force to the movable valve extending in the axial direction of the receiving portion, and a plurality of guide protrusions extending in the axial direction from these shoulders. , The movable valve is fitted to a plurality of concave portions provided on the movable valve and the guide convex portion. It is characterized in that it is attached to the cushion by contacting the shoulder portion.
［作用］ 励磁コイルに非通電のときは、可動弁は流体圧によって
弁座を閉鎖している。[Operation] When the exciting coil is not energized, the movable valve closes the valve seat by the fluid pressure.
励磁コイルに通電すると、磁性材よりなる可動弁が電磁
部に吸引されて弁座を開放する。When the exciting coil is energized, the movable valve made of a magnetic material is attracted to the electromagnetic portion to open the valve seat.
この場合、可動弁は、凹部と案内凸部の嵌合、及び肩部

している肩部を撓ませて弁座を開放する。弁座を開放し
た上記可動弁は、クッションの受部により軸方向の移動
が制限されて、電磁部との衝突が防止される。In this case, the movable valve does not rattle because the movement of the movable valve in the radial direction is limited by the fitting of the concave portion and the guide convex portion and the contact with the shoulder portion, and the movable valve is abutted by the suction force of the electromagnetic portion. Flex the shoulders to open the valve seat. The movable valve having the valve seat opened is restricted from moving in the axial direction by the receiving portion of the cushion, and collision with the electromagnetic portion is prevented.
励磁コイルへの通電を断つと、可動弁は、流体圧と肩部
の復元力とにより、迅速に元の位置に復帰する。When the excitation coil is de-energized, the movable valve quickly returns to its original position due to the fluid pressure and the restoring force of the shoulder.
上記クッションは、受部を構成する筒部の端面に複数の
肩部と案内凸部とを設けたものであるから、小形でかつ
構成が簡単であり、しかも可動弁のガタつきを確実に防
止することができる。Since the cushion has a plurality of shoulders and guide projections provided on the end surface of the tubular portion that constitutes the receiving portion, it is small and simple in structure, and moreover, the rattling of the movable valve is reliably prevented. can do.
